It would be questionable. They have no prospects at SG and Toronto's pick is a guaranteed lottery pick (as per the protections). In order to justify taking an overpaid Perkins until 2015 they could always throw in PJ3 and/or the Dallas 1st.

A Lamb, PJ3, lottery pick, 20ish pick and Perkins bad contract seems like overpaying, but if that's what it takes to grab Gortat (and Dudley to make it work) it might be worth it given that they don't have time to develop young guys.
